Abstract: The specification discloses an improved internal surgical stapler in which staples are pushed by a comb-like ram out of a magazine of a frame and are clinched by an anvil hinged to the frame and releasably latched to the frame by a latch. The latch includes a latch rod having a thumb grip and also provided with a leaf spring catch. The rod normally is in a retracted position in which its forward end is in the magazine. Then, when the user grips the thumb grip and the anvil and squeezes, the anvil is swung toward the magazine to clamp layers to be stapled and the rod is pushed out of the magazine and into a leaf spring latch in the anvil and latches. The rod is splined to the magazine until the end of this latching movement. To release the latch, the thumb grip is turned to turn the rod to move barbs on the rod out of latching holes in arms of the leaf spring catch.

Abstract: The specification discloses an improved multiple suture stapler in which two rows of staples are pushed by a comb-like ram out of a magazine of a frame and are clinched by an anvil releasably latched to the frame. The frame is of one-piece plastic construction and includes a pair of handles hinged to the magazine and having forwardly projecting, hinged arms welded to a push rod connected to the ram. One of the handles has a thumb grip used when the anvil is closed on the magazine. A stapler forming an alternate embodiment of the invention includes a latching rod splined to a frame with a thumb grip serving to push the latching rod into a latch mechanism of an anvil, and also adapted to be manually turned to turn the rod to a latch releasing position.

Abstract: The specification discloses an embosser in which diecast aluminum embossing segments are adhered by epoxy to a roll in rows along long spirals. The roll is driven, and is adjustable toward or away from a resilient backing roll, and co-acts therewith to emboss a web advanced therebetween.
